Application led February 9, 1916. Serial No. 77,241.

vof a new and improved arrangement of forwarding means for carrying articles through sprays orstreams of water for cleaning them. It is one of the objects of my inven.

tion to provide in a machine of this-type removable and interchangeable supports along which the articles to be cleaned are adapted to be carried by the conveyer means, whereby supporting means can be provided as desired forproperly supporting any of a variety of shapes and forms of castings or other articles to be cleaned. It is another object of my invention to provide in a device of this type a new and improved form ofv tank having such conformation as to render it easily cleaned when desired. It is another object of my invention to provide a new and improved arrangement comprising a two-part tank together with means for carrying the lower portion of the carrying set forth in the claims. i

lchain overy the partition between the two sections of the tank without` interference therewith. It is another obj ect of my invention to' improve washing machines in sundry details hereinafter pointed out. The preferred means by whichv I have accomplished my objects are illustrated in the accompanying drawings andare hereinafter specifically described. That which I believe to be new and desire to cover by this application is In the drawings, j

Fig. 10 is an enlarged detail, being substantially' a section taken online 10w10 of Fig. 8.

Referring to the several figures of the drawings in which corresponding parts are indicated by the same reference characters,-

20 indicates a frame supporting a tank -21 comprising sections 22-23 (see Fig. 4)

`on opposite sides of an intermediate wall or partition 24. As is clearly shown in Fig. 4, the bottom .wall of eachV of the sections 22-23 is incllned downward for a considerable portion of its length tow-ard the middle` of the tank, each section having a portion of considerably increased depth at its inner end.

Water is. adapted to be supplied to ther sections 22-23 of the tank through suitable piping 25- from any suitable source, such piping being provided with valves 26 (see. Fig. 2) for controlling ythe admittance of water.

Steam is adapted to be forced into thev water in the tank through piping 27 comprising valves 28 for controlling the enf trance of. the steam. The pipe 27 extends through the wall of the tank, as is best shown in Figs. 3 and 8, near the outer ends of the sections 22-23, the inner ends being provided with improved steam nozzleV mechanisms 29. As is best shown in Fig. 8, each steamnozzle mechanism 29 com-A prisesthree parts each inA the form of a nipple 30 having screw-threaded connection with the pipe 27 by means of `a shortA pipe section 31 (see Fig. 9). Each nipple 30v is provided with a plurality of openings 32 and is provided at its outer endwith a pipe section 33 comparatlvely much larger than the section 31. The section'31 extends into the nipple 30 a shortk distance beyondy 'the openings 32 therein. With the steam nozzle mechanism 29 below the level of the water in the tank, steam is forced throughthe pipe 27 and through the several sections 31 into and through the nipples 30 and out through the sections 33. As the steam escapes from the end of the section 31, the cold water is drawn inward through the openings 32 and is forced out with the steam throughthe pipe section 33, this opperation serving to condense the steam, and to warm the water. I havefound that by the use of a steam nozzle of this type the water in the tank can be very quickly and easily warmed to' the `desired temperature. I have also found that this result is accomplished substantially noiselessly.

The tank is adapted to be drained. by means of piping 34 attached to the tank at two points near the bottom on opposite sides of the partit-ion 24, suitable, valves 35 being provided for controlling thev escape of water. The pipe 34 is also connected with the tank 21 near its ends by means of drain ports 36 whereby lthe level of the water in the tank is automatically regulated and limited to a predetermined maxinmm depth.

The tank 21 is provided with openings in its opposite ends adapted to be closed by valves or gates 37, best shown in Fig. 4, which are adapted to be drawn very tightly into engagement with edges of the openings or securely closing them. Each section of the tank is also .provided with a manhole near its lowermost point at one side, which two manholes are closed by covers or gates 38 similar to the valves ,or gates 37 (see Fig. 1). By means of the openings in the tank at the points indicated, provision is made for quick and easy cleaning of the tank when desired. By reason of the diagonal arrangement of the the bottom of the end portion of the tank the solid matter washed oif of the castings or other articles being cleaned is caused to settle near the center of the tank from which point it can be easily removed.

The means provided for throwing water upon the articles being cleaned comprises two paddle wheels 39-40 ixedly mounted upon a shaft 41 within laterally-extending housings 42-43, the outer ends of which are semicircular in shape, as best shown in Fig. 5. The shaft 41 and the paddle wheels 39--40 are driven in clockwise direction in Fig. 5 by means of a gear 44 mounted on said shaft meshing with va pinion 45 fixed upon a shaft 46 journaled between said housings 42-43 and driven by a motor 47 by means of a belt 48 and pulleys 49-50, the motor 47 in the construction shown being mounted on top of the tank 21. By the rotation 'of the paddle wheels 39-40 in clockwise direction in Fig. 5, a considerable amount of water is carried upward within the curved outer ends lof the housings 42-43- and thrown withconsiderable force to the right in Fig. 5 into the tanks 22-23. For the purpose of breaking up and scattering somewhat the water thrown by the paddle wheels 39-40'1 have provided a plurality of 'downwardly-extending arms 51 spaced at intervals alongside the paddle wheels 3940 as is best shown in Fig. 4.

The means for conveying the articles to be washed past the paddle wheels 39-40 comprises an endless chain 52 revolving about sprocket gears 53 54 ixedl y mounted upon shafts 5556, respectively, near opposite ends of the tank 2 1. The shaft 55 extends through the wall of the tank 21, as shown in Fig. 8, being provided on its outer end with a sprocket gear 57 by which the shaft 55 is adapted to be driven from an other shaft 58 through the medium of a sprocket gear 59 mounted upon said shaft 58 and a sprocket chain 60 connecting the gears 57 and 59. The shaft 58 in turn is adapted to be driven from the shaft 4l through the medium of intermeshing spiral gears 61--62 mounted upon the shafts 41 and 58 respectively. Upon the rotation of the shaft 41A Jroi-'driving the paddle wheels 39-40 in clockwise direction in Fig. 5, the spiral gear 62 will be driven in clockwise direction in Fig. 10, causing a like rotation of the gear 57 in Fig. 2,- serving to drive the upper portion of the chain 52 toward -the left in Fig. 4.

' gears (31-62 properly lubricated, and the housing members (i4-65 are adapted to prevent objectionable splashing of the oil as well as serving as a guard for the gears (ai- 62. y

For enabling the lower portion of the chain 52 to pass freely over the upper edge of the partition 24, I have provided diagonally-disposed slidewiays 67-68, theouter ends of which extend below the surface of the water in position to receive any down wardly-extending portion of the chain 52 for carrying it upward over the partition 24.

For slidably supporting the/,a/r/ticles to be cleaned so as to enable them/,to be moved by the chain v52 lengthwise of the tank 21 past the paddle wheels 40f-39, I have provided a plurality of longitudinally-extending bars 69 supported by transversely-extending` bars 70 upon which the longitudiwilly-extending bars are-fixedly mounted. As is best shown in 'Fig'. 5, the bars 70 are suitable cleansing agent, and with the secadapted to be of such a shape as to support the longitudinally-extending bars 69 in suitable position for providing an appropriate slideway for the particular type of casting or other device being cleaned. In order to render the bars 69 removable, the bars 70 are removably supported in position, a removable support being provided in the construction shown by means of slotted brackets 71 mounted upon the side Walls of the tank froln which the -bars 70 are adapted to be lifted as desired. The transverse bars 70 also serve to support a channel iron 72 inwhich the upper length of chain is adapted to slide. The chain 52 is provided with a plurality of hooks or brackets 73 secured at intervals therealong adapted to engage an article placed upon the longitudinally-extending bars 69 as they are carried about with the chain 52, and to slide such article toward the left in Fig. 4 longitudinally of the tank 21.

With the section 23 of the tank filled with Water of the proper temperature and provided with a suitable soap, acid, or other tion 22 of the tank preferably filled with clean rinsing water, and with the paddle wheels 39-40 being driven by power from the motor 47, and with the chain 52 being `driven as before indicated, a casting, such as the casting 74 shown in dotted lines in ,Fig 5, is placed upon the ends of the lonitudinally-extending bars 69, whereupon it 1s carried forward by one of the hooks 73 of the chain 52 past the paddle wheels 40--39, receiving a thorough cleansing and subsequent rinsing as will be readily understood. Whenever it is desired to use the machine for a different type of casting, the chain 52.

is disconnected at some suitable point and the framework comprising the longitudinally-extending bars 69 and the transverselyextending bars 70 is lifted out of position and another frame-work is substituted therefor having longitudinally-extending bars so positioned .relativen to each other as to p rovide an appropriate support for such casting.

I have found in practice that my device is highly efficient for cleansing castings such as are used in automobile construction, but I do not wish to restrict myself to this particular use for my machine.

So far as I am aware, I am the first in the art to provide a single chain for carrying castings orother articles to be washed along two tanks one adapted to contain a cleaning agent and the other adapted to contain rinsing water, and my claims are to 'be construed accordingly. 4

What I claim as myi invention and desire to secure by Letters Patent, is-

1. In a washin machine, the combination 35 of two tank sections adjacent to each other and separated by a partition rising above the level of the water in said sections, an endless eonveyer adapted to travel over said two tank sections at or 'near the surface of the water in said tank sections, means above the surface of the water in said tank sections and cooperating with the upper portion of said conveyer to conduct articles to be washed over said tank sections, and means for directing the lower portion of the conveyer over the partition between said tank sections.
